Hidden Twin Reshapes the Fate of a LMC Red Supergiant

Astronomers reinterpreted the puzzling behavior of the red supergiant WOH G64 in the Large Magellanic Cloud, finding it is not rapidly dying but part of a binary system with a hotter, smaller companion that interacts with the red star’s extended atmosphere. New optical spectra from SALT show strong titanium oxide bands indicating a cool atmosphere, contradicting claims it was turning into a yellow hypergiant. The strange emissions and the recent dust cloud are explained by material being pulled from the red giant and forming structures around the companion, not by an imminent collapse. The result is a dramatic reminder that binary interactions can mimic signs of stellar death while the star’s evolution continues, with a future supernova still possible but not imminent.
